E|-------------------|
B|-------------------|
G|-------------------|
D|-------------------|
A|-2-2-4-2-2-2-4-2---|
E|-0-0-0-0-0-0-0-0---| Etc.

But the G in the intro and at the beginning of the verses is more of a riff, and is played like so:

E|------------------------|
B|------------------------|
G|------5-3-5-3~-5-3-5-3~-|
D|-5x-x-5-3-5----5-3-5----|
A|-5x-x-------------------|
E|-3x-x-------------------|

And that's the explanation, here's the chords:
